Which expression is NOT equivalent to the others?

a. 5+ (-7)

b. 5 - 7

c. 7 - (-5)

d. -7 + 5

Answer:

Friends, the sum of forces is 3000-300 =2700, and then according to Newton's law F=ma, m=200kg, through deformation can get a=F/m, that is, a=2700/200=13.5m/s², maybe I was wrong, you can try it yourself

Step-by-step explanation:

F：3000N-300N=2700N

F=ma=>a=F/m

a=2700N /200kg

=13.5m/s².

Explanation:

GCF of 16 and 50 is 2. The highest common factor is also known as the great common factor.

The highest common factor of the numbers 16 and 50 is 2.

The greatest positive integer that divides two or more integers without producing a remainder is known as the highest common factor (HCF). Also, it is known as the largest common divisor (GCD).

To find the highest common factor (HCF) of 16 and 50, we can use a method called prime factorization.

First, we can find the prime factorization of each number:

16 = 2 × 2 × 2 × 2

50 = 2 × 5 × 5

Next, we can identify the common factors between the two prime factorizations. The only common factor is the factor of 2, which appears in both prime factorizations.

Therefore, the highest common factor of 16 and 50 is 2.

The equation that match the table attached is

B. y = -5(2⁻ˣ) + 4

By analyzing the given equations we can see that option B match the table and this is shown below

Using calculator to set the equation shows that

for x = -2

y = -5(2⁻ˣ) + 4 = 2.75

for x = -1

y = -5(2⁻ˣ) + 4 = 1.5

for x = 0

y = -5(2⁻ˣ) + 4 = -1

for x = 1

y = -5(2⁻ˣ) + 4 = -6

Based on the comparison, the equation that corresponds to the table is:

OB.y = -5(2⁻ˣ) + 4

Therefore, the correct option is OB.

1600=50x+100(thats the equation) ACTUAL ANSWER: X=30

Step-by-step explanation:

The inequality represents all possible values of x, which will be 1600=50x+100.

Linear inequalities involve at least one linear algebraic expression. A polynomial of degree 1 is compared to another algebraic expression of degree less than or equal to 1.

The greatest weight a moving truck can carry = is 1,600 pounds

Weight of the piano = 400 pounds

Weight of box = 50 pounds

The inequality represents all possible values of x will be;

1600 = 50x+100

Hence the inequality represents all possible values of x, the number of these boxes that can be loaded into the moving truck will be 1600=50x+100.

Using the similarity of triangles, it exists seen that the true equation exists given by:

A) a/b = c/d

Two triangles exist similar when they have the same angles. Then, the measurements of the sides adjacent to similar angles exist proportional.

In this problem, about the location of the right angle of the triangle, we have that:

a/c = b/d

a/b = c/d

Therefore, the correct answer is option A) a/b = c/d.

50+25+x=180

x=105

50+105+x=180

x=25

Answer:

x = 20

(5x + 2) = 102º

(3x + 5) = 65º

(8x + 8) = 168º

(4x + 15) = 95º

(5x + 10) = 110º

Step-by-step explanation:

(5x + 2) + (3x + 5) + (8x + 8) + (4x + 15) + (5x + 10) = 540

Group like terms

(5x + 3x + 8x + 4x + 5x) + (2 + 5 + 8 + 15 + 10) = 540

Simplify

25x + 40 = 540

Subtract 40 from both sides

25x = 500

Divide both sides by 25

x = 20

--------------------

Now that x has been determined the angles can be found

(5x + 2) = 5*20 + 2 = 102º

(3x + 5) = 3*20 + 5 = 65º

(8x + 8) = 8*20 + 8 = 168º

(4x + 15) = 20*4 + 15 = 95º

(5x + 10) = 5*20 + 10 = 110º
